Ethernet optical fiber mutual conversion device in intelligent terminal PD fast charging supporting USB connection

Abstract

The invention provides an Ethernet optical fiber mutual conversion device in intelligent terminal PD fast charging supporting USB connection, relates to the technical field of communication transmission, and solves the problems that switching of the use states of a USB cable and a plug and collision protection cannot be achieved through structural improvement, auxiliary fixing of the USB cable cannot be achieved while switching of the use states of the USB cable and the plug is achieved, and falling or poor contact caused by unintentional touch cannot be avoided. The Ethernet optical fiber mutual conversion device in intelligent terminal PD fast charging supporting USB connection comprises a shell; and a plug is slidably connected in the shell. A sliding sleeve is connected with a connecting rod in a welding manner, and when the sliding sleeve is pushed forwards by 3cm, the plug is exposed, and the USB cable is extruded. Therefore, auxiliary clamping and locking of the USB cable are realized, and poor contact or falling of the USB cable caused by unintentional pulling of the USB cable is prevented.

Description

technical field [0001] The invention belongs to the technical field of communication transmission, and more specifically relates to an Ethernet optical fiber inter-converting device in a PD fast charging of an intelligent terminal supporting USB connection. Background technique [0002] Ethernet is a computer local area network technology. The IEEE 802.3 standard of the IEEE has established the technical standard of Ethernet, which specifies the content of the physical layer connection, electronic signal and medium access layer protocol; the current multi-Ethernet photoelectric converter is implemented through the converter Realize the exchange of Ethernet data and optical data signals. [0003] Such as the application number: CN200910111401.3, a multi-Ethernet photoelectric conversion device and optical fiber data sending and receiving method of the present invention, by judging the number of parallel data bits m that can be processed by the serial-to-parallel conversion o...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides an Ethernet optical fiber interchanging device in the intelligent terminal PD fast charging that supports USB connection, to solve the existing problem that the county postal device is easy to insert the plug joint and the plug of the USB cable when placing it. The charging terminal of the charging terminal is bumped and damaged, and the switching of the two usage states and bump protection cannot be realized through structural improvement, and the auxiliary fixing of the USB cable cannot be realized while switching the usage status of the two, so as to avoid unintentional contact. Touching leads to falling off or poor contact; moreover, the existing device cannot realize the rolling of the USB cable and automatically realize the problem of wiping and cleaning the plug connector of the USB cable while rolling.
